This paper focuses on an online video based correction system for language learning. The prototype system using the proposed model supports learning between a native English teacher and a non-native learner using a videoconference system. It extends the videoconference system so that it can record the conversation of a learning scene. If a teacher edits the video to include explanations, the video can become very useful as teaching material. However, in ordinal video-editing systems, it is difficult to show edited parts. Therefore, this paper proposes a video correction system and focuses on the online video-editing model. (Contains 14 references, 1 table, and 4 figures.) (Author)
